GAS-BURNING APPLEANCE.

SPECIFICATION forming part of Letters Patent No. 786,647, dated April 4,1905.

Application filed February 19,

;To all whom, it may concern:

Be it known that I, EDWIN CHARLES J ONES, of Woodstock, in the county ofOxford and Province of Ontario, Canada, have invented certain new anduseful Improvements in Gas- Burning Appliances; and I hereby declarethat the following is a full, clear, and exact description of the same.

To effect a practically perfect combustion of hydrocarbon or othercombustible gas,it is necessary to combine with it oxygen-gas or airproportionate in volume to the volume and quality of the combustible gasemployed as the heating or illuminating agent. To carry this part of theinventioninto practice, I employ a hollow burner-tip having therein adistributing-chamber in the bottom of which is an inlet-port for theadmission of the mixture of gas and air and in the top of which are aseries of outlet-apertures and an imperforate portion opposed to andprojecting beyond the inlet-port to baffle the inflowing mixture of gasand air and effect its even distribution to all parts of themixing-chamber to equalize the pressure of the same as it passes throughthe outlet-apertures. To the inlet-port is connected the burner pipe,fitted with the mixer, which consists of a gas-injecting nozzle opposedto the bore of the burner-pipe, an air intake or inlet aperture oropening in juxtaposition to the injecting-nozzle, and a tubular valveadjustable on the burner-pipe to vary the dimensions of the air-intakeopening or aperture and regulate the volume of air admitted therethroughto mix with the inflowing combustible gas.

The second part of the invention relates to the gas-burner, which isinclosed, preferably, by a substantially gas and air tight casing havingan air-inlet port below the gas-burner controlled by an adjustable valvefor the admission of air to the interior of the heater to not onlysupport the combustion of the mixture of combustible gas and air, butalso to create a draft through the heater to force the heated gases tothe outlet-port, which is preferably connected with a second heaterhaving an inlet-port for the admission of the heated gases from thefirst heater and an outlet-port for the exit of the same therefrom to athird I 1904. Serial No. 194,455.

heater similar in all respects to the second, and so on to the lastheater of the series, the outlet-port of which is preferably connectedwith the chimney outlet-duct or outside atmosphere. To prevent theradiated heat burning or scorching the supporting-base for the heater,the bottom of each heater is lined with asbestos, mineral wool, or othersimilar nonconducting material, while the sides and top of the heaterare provided with apertures fitted with mica or other translucentheat-conducting closures for heat radiation, as well as for illuminatingand ornamental purposes.

' For a full understanding of the invention reference is to be had tothe following description and to the accompanying drawings, in whichFigure l is a side elevation of the heaters and burner. Fig. 2 is a sideelevation of the burner. Fig.3 is a longitudinal section through theburner. Fig.4 is a vertical section through the heater and burner; andFig. 5 is a detail view of the bottom of the heater, showing theair-inlet port and controlling-valve.

Like letters of reference refer to like parts throughout thespecification and drawings.

The gas is discharged from the gas-main through the gas-injecting nozzle6 into the burner-pipe c and mixes therein with the air or oxygenadmitted through the intake or inlet aperture or opening (Z. The intakeor inlet aperture or opening (Z is preferably formed in the burner-pipeo in juxtaposition to the injecting-nozzle 6 to enable the air and gasto inter-mix as they flow through the burnerpipe. To control the volumeof infiowing air, the outer surface of the burner-pipe 0 contiguous tothe opening is screw-threaded, and mounted upon the burner-pipe is atubular valve f, having its inner face screw-threaded to intermesh withthe screw-threaded surface of the burner-pipe and longitudinally adjust.the tubular valve thereon to regulate the volume of air admitted throughthe intake orinlet aperture or opening to with the combustible gasdischarged from the nozzle into the burner-pipe. Owing to the variationsin the quality and pressure of the gas, it is necessary to provide forthe regulation of the admission of the volume of air to the burnerpipe,as an excess of air would have the eii'ect l by means oi a pipe '21,from the outlet s oi the of destroying the combustible properties oflirst heater to the inlet 1.0 of the second heater,

the gas, while an insullicient quantity would not eii'ect a perfectcombustion. 'lhe burnerpi pc 0 as it approaches the burner increases indiameter, so that the combustible gas and air or oxygen can expand andintimately mix before passing to the mixing-chamber 7t oi theburner-tip, where the intermixing of the air and is con'ipleted. In thetop Z for the mixing-chamber 7b is an imper't'erate portion j, opposedto the inlet-portlu to hailie the inflowing mixture of air and gas fromthe burner-pipe and evenly distribute it to all parts of themixing-chamber to equalize its pressure as it passes through the outletsZ, surrounding the imper'lorate portion j. By reference to Fig. 5 itwill be noticed that a battle 7) for the flame and gases extendsupwardly from the cente' of the imperlorate portion of the burner-topand when acted upon by the l'lames intensifies the heat radiation andincreases the heating value of the appliance by directing the heated gasto the sides of the casing.

By reference to the drawings it will be noticed that the burner islocated within the heater, preferably in close proximity to theheater-bottom m, and surrotmding the opening for the burner-pipe 0 inthe heater-bottom 11/ is an air-inlet 0, controlled by an adjustablevalve 1) to regulate the volume of air admitted to the interior of theheater. The sides and top 1', which may be of any suitable design, arepractically air and gas tight to prevent the escape of the heated gasesor any part thereof from the interior of the heater except through theoutlet in the heater-top. In the sides and top are openings t, fittedwith translucent closures, preterably oi mica or other non-combustibleheatradiating material, to not only add to the illuminating andornamental qualities of the apparatus, but also to increase itsheat-radiation properties.

The heated gases are conducted,

through which they circulate and pass to the outlet 11. and from. thereto the inlet of the third heater, and so on to the outlet oi the lastheater, from which they are conducted to the chimney outlet-duet orother duct leading to the outer atmosphere. The discharge of the gasfrom the outlet .9 may, if desired, be controlled by a damper 3 placedin the outlet x of the first heater or in the outlet of any of the otherheaters of the series. The bottoms of the heaters are fitted withsupporting-feet to raise the heater a sufiicient distance from thesupporting-base to allow of access to the air-inlet valve 1) and furtherassist in preventing the radiation of the heat from the heater-bottomsetting tire to the supporting-base or scorching it, the feet beingassisted in this respect by a lining (1/, of asbestos, mineral wool, orother material of similarnon-conducting properties.

Having thus fully described my invention, what i claim as new, anddesire to secure by Letters Patent, is

In a gas-burning appliance the combination oi a heat-conducting casinghaving an air-inlet and an adjustable valve to control the airinlet witha burner within the heat-conducting casing consisting of amixing-chamber having a bottom with an inlet-port and a top having animper'forate portion opposed to the inlet port and a perforate portionsurrounding the impert'orate portion, a halile ex; tending upwardly fromthe burner-top and a burner-pipe fitted to the inlet-port of themixing-chamber, and a heat-insulator interposed. between the gas-burnerand the casingbottom.
